Hi All,
As you might have understood with my so many questions :) I am looking at
the capabilities of Drools and our team is looking at a comparitive analysis
between Drools and ILOG
One of the feature which is greatly desired is natural language editor. So I
am planning to create my own DSL

Hey Kris,
I run the test and had some problems:
1. First I had empty workitems. I fix it by adding this line after creating
and loading the session:
ksession.getWorkItemManager().registerWorkItemHandler(Human Task,
handler);
But how could the test passed in your environment without this lines?
If it works fine with an and operator then I’d imagine that startDate
$regDate returns false, with an this would abort evaluation immediately but
with an or it would mean that startDate endDate is evaluated and so
presumably it is this bit that is throwing the NPE. I’d imagine that the most
Hi Thomas
Thanks your prompt reply. I am sure all three attributes are NOT null. I have
tested them before sending question to mailing list. If you want, I can send
complete sample code and you can try it at your end.

Have you got the stack trace, that may give a clue? Also what are the actual
values of start date and end date?

Please try this rewrite of the 2nd CE:
Segment ( $endDate : endDate, startDate $regDate || startDate $endDate )
and report the outcome to the list, together with the Dools version
you are using.
Thank you.

In this scenario I do have typical Order and Items data structure. I want to
implement various business rules where I want to check both Order attributes
and Item attributes together.
Order [ Date, Discount, Amount, Customer, Type, Items]
Item [ Quantity, Rate, ExpiresDate, Grade ]
I am trying
Discount is a field of Order and must not appear in an Item(...).
Probably you want:
Order ( $discount : Discount 10,...
Also, most likely, all your fields need to be written with a lower case
initial letter,
Order ( $discount : discount 10, $items : items)

Hey, I haven't been following this thread, but you can use Joda Time to get
much better, easier results. For instance, you can add 1 month to a DateTime
by using a new Period(P1M) [that is, a period of 1 month] - all done
according to ISO8601 standards, so it works flawlessly, including
Hey Kris,
I created a little demo-process with two subprocesses which covers my
problem. The flow should be Start - Super - Sub1 - Sub2 - Sub1 - Super -
End. But at runtime it is only Start - Super - Sub1 - End.
I think the test case is self-explanatory.
Thank you for your efforts!
Regards
I was about to suggest this. :) And one advantage of using joda time is that
version 1.6 is already included as a dependency of drools.

Hi W
I know about case sensitivity issue. How can I combine both Order and Item in
one condition. I tried all possibilities but getting syntax error.
For example:
Order ($items : items, $discount : discount 10, Item(grade 3)
from $items) // gives error
Can please code this condition
Segment ( $endDate : endDate, startDate $regDate || startDate $endDate )
even does not work. I am using verstion 5.0.1. All dates are java.util.Date and
values in sample fact are:
regDate = Fri Aug 01 00:00:00 BST 2008
startDate = Tue Sep 01 00:00:00 BST 2009
endDate = Fri Jul 30 00:00:00
I think what you are looking for is the following. Someone please
correct me if I am incorrect.

Order($discount : discount 10, $items: items)
Item(grade 3) from $items
then
System.err.print(Discount is not allowed with items having grade 3 or
higher);
This would fire when an

I'll try this but what if I have more complex condition e.g.
Order ($discount : discount, $items : items)
Item(grade 3 (quantity 5 || $discount 10)) from $items

You really ought to read all the pertaining sections in the Drools Expert
manual and experiment. Nobody can write complex rules without some exercise.
